Peter Krentz delivers a very calculated, assured, methodical and comprehensive argument which unpicks the contrary assertions of more modern historians, by challenging what has seemingly become the status quo of deriding contemporary historical sources, largely under the premise that they were prone to exaggeration (whether by personal, political or other influences). What the author achieves in his analysis, is an argument that accepts potential for bias and establishes the fact that no source is immune to criticism but that equally the evidence, in all its multifarious forms, together with a logical analysis of events, does (in his argument at least) tend to support the original claims recorded by Herodotus of the battle of Marathon.
The book is at no point preachy or derisive of other sources and acknowledges and puts forth other seemingly valid arguments and principles, which ostensibly bolster rather than undermine his argument and all of which are critiqued thoroughly and effectively but done so whilst never losing track of the main subject matter. This is a prime example of intelligent critique and highlights the importance of historical analysis as well as the necessity to review material continually in order that we never become complacent or arrogant in our accepted view of the past, as everything should be open to interpretation, for the very credibility of the discipline.
I prefer not to indulge too far into an analysis of the argument proposed as the author does this quite effectively themselves. What should be said however, is that this is a tremendously informative, objective and reasoned assessment of the battle of Marathon and the events surrounding it, which encompasses a mass of evidence whilst addressing the various perspectives involved. It also has a wider relevance with regard to how we address issues of contention today and how contrary opinions should be open to discussion and objective analysis in much the same way that our past is, rather than imposing and accepting rigid dogmas with which to make our arguments.
This book will provide excellent reading for the most devout as well as the more casual enthusiast, it's easily digestible and comprehensive in equal measure. I implore you to read it.
